Suffix -MENT is a consonant suffix. It is a “noun maker” because when it is added to the end of a base word, it changes it to a noun, most often naming the result of an action, as in “agree” to “agreement”.
Suffixes at the ends of words are not typically accented and Suffix -MENT changes to schwa in speech.
